When case formatting

[meoyawn]

ktlint says I have unnecessary spaces here

when {
    true         -> 1
    true && true -> 2
    else         -> 3
}

but these are not unnecessary

@adelnizamutdinov ktlint does not allow vertical alignment on purpose* (there are exceptions like class/function arg list or comments but when expression is not one of them). Intellij IDEA formatter (with default settings) is more or less doing the same.
